HS-GC-IMS analysis and fingerprint study of volatile organic compounds in five species medicinal and edible Chrysanthemum morifolium Ramat.

Abstract

Objective: To understand the difference of cumulative content and species of volatile organic compounds （VOCs） in five different species of Chrysanthemum morifolium Ramat.. Methods: In this study, five different species of Chrysanthemum morifolium Ramat., namely, Jinsihuangju, Huangju, Hangbaiju, Boju, and Gongju. The differences and variations of the fingerprints of volatile organic compounds （VOCs） in different species of Chrysanthemum morifolium Ramat. were studied by headspace-gas chromatography-ion mobility spectroscopy （HS-GC-IMS）, combined with cluster analysis and relationship matrix in the form of data visualization. Results: There were significant differences in VOCs among different varieties of Chrysanthemum morifolium Ramat. （P＜0.05）, and the similarity between them was less than 70%, and all of them had their own unique volatile organic components; the five kinds of Chrysanthemum morifolium Ramat. in the order of high to low VOCs content were: Gonju, Jinshi Huangju, Huangju, Boju, and Hangbaiju. Conclusion: HS-GC-IMS can make up for the shortcomings of conventional VOCs detection, making detection more data basis and support, and providing theoretical basis and data support for the differentiation and identification of different varieties of Chrysanthemum morifolium Ramat..
